Climate Change: How many climate warnings do we need?

Millions of people marched yesterday demanding immediate action to try to avert climate collapse proportionate to the threat that catastrophe poses to our civilisation’s survival. Whether the world’s governments — especially those in America, China, and India — stir themselves from their stupor and respond is, amazingly, still an open question.

Several thousands of those marchers, mostly students, marched in Dublin, Cork, and Belfast. Some did so in defiance of school authorities, which suggests a startling lack of awareness around the reality facing us in our schools.
